Abstract

As the workplace evolves in our vertical cities, the need for “think spaces” and the public realm to meet, create and innovate will become integral to tall buildings. These people places are designed to address the social challenges and enhance the co- working environments which are emerging in the dense urban context of our future cities. The design of sky terraces and the “spaces between” offer a greener, more humane and smarter work environment for the future. The public realm should no longer be held down, fixed to the ground plane, but rather become part and parcel of the upper levels of our workplace centers. These collective spaces in our workplace centers must provide a three dimensional matrix of connected and identifiable platforms to leverage the open and progressive future way of working. This will enable social networking and idea sharing, and create multi-dimensional, multi-level business incubators for innovation and creativity. The BCO ( British Council of Offices) has performed a landmark Wellness Matters Report which provides an exemplary roadmap for the future of the workplace. Our future vertical cities must also provide for serendipity in the workplace; a key attribute to drive the information exchange and collaboration that are proven to provide positive and progressive business outcomes. In addition to demonstrating examples of existing built work and the concept of the integrated vertical public realm, the presentation also will consider and define wellness in the workplace as a critical factor in our design strategies and our future workplace environments Hanging Gardens, Roof Terraces and the Vertical Plazas; designed for interchange, wellness, animation and collaboration.

1.2. Evidence Based Data As the UK’s leading forum for the discussion and debate of issues affecting the workplace sector, the BCO ( British Council of Offices ) has performed a landmark Wellness Matters Report which provides an exemplary roadmap for the future of the workplace. Drawing upon diverse sources of guidance, including Harvard University’s ‘9 Foundations of a Healthy Building’2, the NHS’s ‘Creating Healthy Work Places’ campaign and resources from the UK Health & Safety Executive and Public Health England, the report refers to sustainability (BREEAM, Ska and LEED) and wellness (WELL and Fitwel) rating systems. The report suggests that emerging occupant demands, new performance standards and third party health & Figure 3.

The workplace plays a crucial role in the overall health Over the past few years, there has been a significant and wellbeing of its occupants, particularly in relation to migration of the world’s populations to urban contexts, the and location and community context, a green and which has resulted in these cities’ growth and densification. sustainable environmental and spatial quality and the According to a study carried out by the United Nations, culture it promotes. (See Figure 4) 54 percent of the global population live in cities and this is presumed to increase to 66 percent by 2050 or an equivalent of 2.5 billion more urban dwellers, which could see the growth of even more new cities. The Bay Area of California has seen tech companies move from campus style workspaces in Palo Alto’s Silicon Valley to the tighter urban environs of downtown San Francisco. Yet, this open plan typology is at odds with the city’s smaller footprints. The demands for more collaborative and inclusive spaces but dense yield means that it is time for our vertical environments to answer this future workplace requirement. As the workplace continues to evolve in our vertical cities, the need for these “think spaces” in the public realm to meet, create and innovate will become integral to tall buildings.

This will often include leveraging new multi-level plazas, gardens and meeting place rooftop terraces to capitalize on green spaces, views, weather and also time for reflection. Other components that need to be addressed for a successful vertical workplace are: Integration: A key objective within the workplace is to design vertical connectivity and compelling spaces for interaction. Both these can be encouraged by elements such as enhanced interior atriums, interconnecting stairs and atrium facing terraces, as well as bridges, spaces for gathering and external vertical parks. Spatial Quality: Sky terraces and communal spaces are often used to create a place for amenities and informal meetings. These active hubs can also create a link between different work areas and provide social or solitary respite. Additionally, they enhance already existing functional qualities of work settings and bring together groups and teams allowing for cross pollination Flexibility: If buildings are to have any legacy, adaptability is crucial for the constantly evolving needs of modern workspaces, which has resulted in the growing trend for mixed-use facilities. The vertical workplace must also have the ability to scale up or down on office needs, and retail and/or service needs. For example, office spaces Figure 5.

2.1. 151 North Franklin, Chicago For the design of 151 North Franklin, a spec office tower in Chicago, design firm, John Ronan Architects asked: “How do you pull the city into the building? And conversely, how do you make it better?” [Architect Magazine, 2019]. Instead of focusing on the building’s form, they took a more urban holistic approach, connecting the building’s public spaces to the city around it. Starting with the existing pocket park located across the street, the scheme extends the concept of green space right through the building, with a plaza and visually open lobby at the base, a terrace on the second level and a glassed-in deck on the top floor. (See Figures 4 and 5) Moving away from the conventional ‘mausoleum’ style lobby, specifications and materials are a key element in Figure 6. 151 North Franklin, Chicago. 74 Stephan C.

Our historical research indicated that on this site until 1910, there was a small cul-de-sac known as Percy Square, in consort with open permeable double height foyers and magnificent cantilever entry areas with a truly grand open air stair entering the site from Penton Rise. The three workplace and residential building com- ponents sit above a lower ground level which features shops, cinemas, a fitness centre and workshops.

The two towers rise to 50 and 39 storeys respectively and are connected by three large bridges, clad in copper-coloured aluminium louvres. Each bridge contains a specific set of facilities shared between the north and south tower, such as a health centre, a library, and a running track that loops between the two buildings.

The building is a Vertical Village, built to support and nurture its population of 12,000 inhabitants. Higher ceilings, increased daylight control, better fresh air and amenities at different levels, combine to support individuals, in traditional and new ways of working. Outside of office area, approximately 100,000 square feet is dedicated to facilities that aim to improve the everyday experience for the building’s users and the public. These include retreat areas for relaxation and exercise, informal meeting spaces for both small start-ups Figure 11. Penton Place, Central London. 76 Stephan C.

This urban design solution is reinforced by a newly created lineal park derived from the orien- tation, materiality, planting and serene environment created by Paley Plaza in Central Manhattan, constructed in the 1960’s. However, in a break from the current status quo for office destinations, the offer of a quality public realm is not confined to ground plane. At Cutlers Plaza the public realm is extended up thru the two building components to a variety of accessible elevated hanging gardens, vertical plazas and cascading roof top terraces.
